How Much Does It Cost to Paint a Sauna? Painting a sauna in the United States typically costs anywhere from $300 to $1,200 or more, depending on factors like size, materials, and whether you do it yourself or hire a local professional. Doing it yourself will naturally be cheaper, while hiring pros for prep and painting can increase costs. A small sauna (around 40–50 sq ft) might run about $300–$600, whereas a larger sauna (around 80–90 sq ft) may cost $700–$1,100 or more—especially if you opt for thorough sanding and multiple coats of specialty paint or wax. A small sauna (around 43 sq ft) can cost about $200–$400 in materials if you do it yourself. A larger sauna (65–86 sq ft) might cost around $500–$800 for paint or protective finishes, especially if you treat walls, ceiling, and benches. Professional services can run from $800 up to $1,200 or more, depending on prep work, the size of the sauna, and the products used. If you’re opting for a full refinish with thorough prep (cleaning, sanding, priming) and applying high-quality, heat- and moisture-resistant products, costs may rise accordingly.

Factors Affecting Sauna Painting Costs Sauna SizeLarger saunas require more materials and labor time. Prep WorkDark or heavily stained paneling may need thorough cleaning and sanding, especially if you want to lighten the color. Surfaces to PaintPainting walls, ceilings, benches, and doors all affect total costs. More surfaces = more materials + labor. MaterialsHigh-quality, moisture-resistant paints or specialty sauna products can be pricier but last longer. Professional LaborHiring a contractor or professional painter ensures expertise and a warranty on the work, but labor costs can easily increase your total. DIY or Hire a Pro? Painting or staining a sauna can be a manageable DIY project if you have basic painting skills and want to save money. However, professionals typically know how different paints perform under high heat and moisture. They also have experience with proper surface prep and can recommend the best products for your sauna’s condition. Pros of Hiring a Professional Speed and cleanliness: Pros can often complete the job more efficiently. Correct product choices: Avoiding the wrong type of paint or finish. Warranty: Many contractors stand by their work if issues arise later. Cons of Hiring a Professional Higher cost: Labor rates in the US can range from $35 to $70 per hour or more. Scheduling: You’ll need to align the project with your contractor’s calendar. If you don’t want to tackle the project yourself, contact local painters or contractors who have experience with sauna finishes. They can assess your sauna’s condition and recommend the right paint or stain. Common DIY Pitfalls Using the Wrong PaintStandard interior paints usually aren’t formulated to handle high temperatures or moisture. Stick to sauna-specific waxes, sealers, or breathable high-heat paints (for example, High-Temperature Protective Coating or Sauna Wax). Applying Too Many CoatsA thick layer of paint can trap moisture and prevent the wood from “breathing,” potentially causing issues like mold or unpleasant odors over time. Skipping a Test PatchStains, tinted waxes, or paints might look different on the actual wood than in the can. Always test on a small, inconspicuous area first. Inadequate Mold/Mildew PreventionExterior or unheated saunas can be prone to mold, especially if the wrong coating is used. Consider a mold-preventative wash or additive for areas at risk. For best results, consult the staff at your local hardware or paint store. They can suggest the right product lines and even provide brochures or step-by-step guides. You’ll also find plenty of sauna-painting tutorials on YouTube and DIY home improvement forums. Choosing the Right Finish Many US hardware stores sell specialized products formulated for high-heat, high-humidity environments. Many brands offer protective coatings designed for saunas, helping you achieve a durable, safe finish that won’t off-gas harmful chemicals at high temperatures. See our list of best sauna cleaners and finishing products Sauna Paint (Acrylic-Based)Heat-resistant acrylic formulas can work well on walls and ceilings if specifically labeled for sauna use. Waxes or OilsThese preserve the natural wood look and prevent too much moisture from soaking in. Protective Wax is an example of a breathable finish that helps wood maintain a natural feel. Stains or Semi-Transparent FinishesLet the grain show through and can be tinted to your preferred shade. Check product labels for details of low-VOC certifications if you’re concerned about indoor air quality. Prep Work and Cleaning 1. Cleaning and Sanding Wash the walls, benches, and any wooden surfaces with a sauna-safe cleaner (e.g., Sauna Cleaner). Rinse thoroughly to remove all residue. Let surfaces dry completely, then lightly sand if needed to ensure proper paint or stain adhesion. 2. Painting or Waxing Walls & Ceiling Apply the product in thin, even layers, following the wood grain. Some finishes require only one coat; others may need a second. Check the manufacturer’s instructions. Observe recommended drying and curing times. 3. Benches & Doors Benches typically do best with wax or oil-based products to avoid a sticky feel under high heat. If possible, remove benches to paint or stain all sides (including the undersides). Protect any glass or hardware on sauna doors with painter’s tape before you begin. 4. Final Checks After the paint or finish cures, run the sauna at a moderate temperature for a short “break-in” session. Ventilate the sauna well afterward to ensure no lingering odors. Refreshing an Older Sauna Watch for previous coatings: Old wax, oil, or paint can interfere with new products, so thorough cleaning and sanding may be necessary. Consider darker finishes: If your wood is yellowed or unevenly toned, a darker stain or tinted wax can achieve a more uniform look. Take time for detail work: Gaps, corners, and hardware areas can accumulate buildup. Clean and sand meticulously for the best result. Painting Your Sauna Step by Step Prep the SurfacesRemove dust, dirt, or old finish residue. Mask off areas you don’t want painted. Apply the First CoatUse a brush or roller suitable for wood, following the grain. Apply thin, even layers of paint, stain, or wax. Let It DryFollow the product’s drying instructions. Sauna-specific products may need 24–48 hours or more before heat exposure. Apply Additional Coats (If Required)Some products only need one coat; others might recommend two. Avoid over-application. VentilateEnsure the sauna is well ventilated during and after finishing. Air out any fumes thoroughly. After the Painting Is Done Once you’ve finished painting or staining your sauna surfaces, allow them to dry thoroughly before your first heating session. If you used products with a strong smell, make sure to air out the sauna well. Most sauna-specific paints, waxes, and stains will include detailed instructions on how long to wait before you heat the sauna, so follow the manufacturer’s guidelines. Disposing of Paint Waste Wet paint is considered hazardous waste. Take leftover paint and used solvents or thinners to a local hazardous-waste collection site. Dried paint and empty cans (with no liquid residue) can usually go in regular trash. Never pour paint or thinners down the drain or into the environment. Keeping Costs in Check If you want to save money on painting or staining your sauna, good planning and some do-it-yourself prep work can help: Schedule and Plan If you’re hiring someone, get in touch during slower seasons (often late winter or early spring) when contractors might offer more competitive rates. Compare estimates from multiple local painters or contractors. Do the Prep Work Yourself Cleaning and light sanding are time-consuming but straightforward tasks you can do on your own. Removing sauna benches or trim ahead of time also helps any hired painter or handyman work more efficiently (and could lower labor costs). Choose the Right Products A sauna wax or stain can be more economical than a fully opaque paint, but it may offer less protection. Breathability matters: an acrylic paint that’s too dense can trap moisture, so always opt for sauna-approved brands like SaunaGeginius High-Temperature Coating or SaunaGeginius Sauna Wax. Test the Color First Always do a test patch of your chosen color or stain to avoid an expensive redo if the shade looks different once on the wood. Material Choices Matter Sauna Wax vs. Opaque Paint: A transparent or semi-transparent wax (or stain) often costs less and preserves the wood’s natural look. However, it usually provides a thinner layer of protection than a high-coverage paint. Consider Leaving Some Surfaces Unfinished: Untreated wood can be fine if you’re not worried about staining or if you prefer the natural look. Keep in mind it may be harder to clean. Beware of Tight-Film Coatings: Some acrylic paints or older oil paints can block the wood’s natural moisture balance. This is especially important if your sauna is in a colder climate or used seasonally. Work Steps You Can Optimize Do Your Own Cleaning & Sanding: This is often half the battle. If you bring in a pro for the actual painting, they can start right away on the finishing coats. Remove and Label: Take out benches and any removable elements. Label screws and brackets to make reassembly hassle-free. Test Your Color: Apply the product to a discreet area first to confirm the final look in your sauna’s lighting. Finding a Reliable Painter or Contractor Ask Around: Friends, neighbors, or local community groups can be a great source of recommendations. Check Reviews: Online platforms make it easy to see if a potential contractor has experience painting saunas or other high-humidity areas. Verify Insurance and Guarantees: Make sure the painter or handyman you hire has proper coverage and offers a clear warranty for their work. Discuss the Details: Confirm the brand of paint or wax they plan to use, the number of coats, and the timeline. Tip: Even if you hire a pro, it helps to know the basics of sauna painting so you can discuss your preferences and ensure the right products are used. What Next? Painting or waxing a sauna isn’t the most complicated home project, but it does require careful product selection and attention to detail: Consider the sauna’s construction (e.g., log walls, heat-treated wood, detailed paneling). If your sauna is left unheated for part of the year, factor that in when choosing a paint or finish. High humidity levels in colder conditions call for breathable, mold-resistant coatings. Avoid Overpaying for Your Sauna Project Compare Multiple Bids: If you’re hiring a contractor, don’t settle for the first estimate. Choose Color & Products in Advance: Plan so you don’t end up rushing into a finish you don’t like. Don’t Overdo the Coats: Many finishes are primarily aesthetic—too many layers can trap moisture. Consider a DIY Approach Where Possible: If you’re comfortable with light carpentry or painting, prepping or finishing on your own can significantly cut labor costs. Final Thoughts Painting or refinishing a sauna can be straightforward if you arm yourself with the right knowledge and products. Whether you do it yourself or hire a local professional, paying attention to prep work and using heat-resistant, moisture-friendly coatings will give you a beautiful, long-lasting result. Enjoy your refreshed sauna!
